Cisco 3750 MQC Based QoS

[ravisambaji]

Hi Friends,

Iam trying to configure MQC based qos on my Cisco 3750 switch. The switch accepts all commands, however when i apply the service policy to the interface it doesn't have any effect. I don't see any matching packets with show policy-map commands, however all my traffic passes through. My ACL was permit any any.

Can any one help me with working MQC based qos configuration example for Cisco 3750 switch.

Regards

Ravi

Hi Ravi,

does it look like that?

Class-map: VOICE-RTP (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name VOICE-RTP

I think the problem comes along with the acl. The corious thing is that I can capture RTP traffic which is tagged DSCP Value and on the core switch I recognize DSCP value changes.

Is it similar to you?
